"Hey Dave, what you doing this weekend?"
"I don't know sis. Why you askin', you need a ride or something tonight?"
"No, I thought you'd like to go to a party, Rachel is having big blowout tonight. The last before we all head off for college in the fall."
"I don't know if I want to hang out with a bunch of high school babies," I teased my sister. I'd had a bit of a crush on her friend Rachel for the last couple of years. I'd also heard rumors about how wild her parties could get. I was definitely up for this.
"We'll all be in college next year, besides I'm not the one that has nothing planned for the weekend. You're the loser that has no plans and needs to be invited to hang with his little sister and her "high school" friends."
"Okay, okay, you win again. I should know by now that I should never argue with you. I never win."
"That's right. Just accept that you're always wrong and you'll feel much better."
I smartly decided to ignore this dig. "So what time is the party?"
"We still have a couple of hours to kill, let's get ready, cause I have a little surprise for you before we leave for the party."
We both went upstairs to shower and dress. Even though I let Mary take the first shower, I was still ready before her. I went downstairs and stared at the TV, while waiting for her to finally finish with her primping.
"Where are you? I need you tell me what you think of my outfit."
"I'm in the TV room. You must be really desperate if you want my advice on your outfit."
"No, I just need a guy's opinion and you're the closest thing available."
"I really never learn, do I? Just come in here and let me see what you've got on." My jaw dropped when Mary walked in. She was wearing a black micro mini, thigh high boots, and tight white tank top. I didn't look closely, but at first glance I didn't think she was wearing a bra. I always knew my sister was pretty, but I'd never thought of her as a "hot" girl before. I guess she was all grown up now. "You're not going to wear that to the party, are you."
"Yes, I am. And you're not going to tell Mom, about it. Normally, I'll wear something less revealing when I leave for a party, but tonight I don't have to stoop to any tricks. Besides, if you rat me out, I'll tell her about you taking X tonight."
"I don't have any, besides I've never taken it anyway."
"Well, I have four tabs that are supposed to be out of this world. Here are your two. Unless you're chicken."
"I never said I was afraid or wouldn't take it. I just said that I haven't, at least yet."
"Well, down the hatch."
We both downed the pills and sat back to wait until it was time to leave for the party. Next thing I knew, the movie I had on was over, which was very strange, because the movie was only half over when we took the X. Somehow, we had lost an hour. I felt funny, yes, I was high, but it was different. I couldn't explain it at the time, and I still can't quite put it into words. But there was something wrong. It was like I wasn't in control of myself. I went to check my watch to see exactly how much time we'd lost in drug induced stupor, but my watch wasn't on my arm. My arm, well it wasn't my arm. It was thinner, and had much less hair than my right arm. Trying to figure out what went wrong, I looked down at my body. I was wearing a dress, well not a dress, but a tiny piece of cloth covering my crotch and pair of fuck me boots.
I looked over to my sister and did series of double takes. I was looking over at myself. It suddenly dawned on me; I was laying in the chaise lounge that Mary was relaxing in when we took the pills.
"Mary, Mary wake up."
I stumbled over to my body, and shook it trying to figure out if I was in a dream or if this was actually happening.
"What is it Dave? Stop shaking me. I'm up."
"What is it? Look at me, what do you see?"
"Huh, what do you mean," Mary moaned as she started to open her eyes. "Holy shit, what's going on?"
I opened the compact she left on the table and held in front of her face. I saw a look of confusion, followed by horror pass across her/my face. It was really bizarre to see my sister's normal facial movements on my face.
"What did you do to me, how did this happen?"
"What did I do? It's your ecstasy or whatever it really was we took."
"I've taken it before and never had this happen. Do you really think I'm dumb enough to take a drug again if it did this before?"
"No, I guess not. But what are we going to do? I think you're a great sister, but I don't want to be you forever."
"Do you think I want to be an virgin dweeb like you? I'll never get laid again if I have to go around looking like this."
"Hey, I didn't say anything bad about you. We just have to figure this out somehow. Who did you get the pills from?"
"Oh, this guy I know at school. If I flirt with him he gives me my shit for free or at a discount."
"How much do you flirt with him? Don't get mad at me, but do you act like a tease around him?"
"Yeah, I guess so ... a little. He asked me out a few weeks ago, and I turned him down."
"Well, I guess that is as likely an explanation as any, but I've never heard of anything that would cause this to happen."
"I can't think right now, I think I have to pee really bad. I'll be back in a minute." She hopped up off the lounge and ran into the bathroom.
The mention of going to the bathroom made me realize that I had to go too. I stumbled up the stairs, not being used to high heels. When I finally got into the bathroom, I pulled down the skirt and the g-string I was now wearing, and started to reach for my dick. There were going to be more issues than I originally figured. Just before it was too late, I sat down on the toilet and emptied my bladder immediately. After I was finished I wadded some toilet paper to wipe myself. Not being intimately familiar with female anatomy down there, I started wiping too far forward and had a very pleasant surprise as the paper rubbed my new clit. I'd never felt anything like that before. It was twenty times better than rubbing the head of my dick. Knowing that I shouldn't Jill off my sister's body, I quickly grabbed another wad and carefully blotted myself to make sure I'd dried myself completely.
I went back downstairs as quickly as I could. I misjudged the penultimate step and started to fall, I tried to catch myself like I normally would, but my sister's body wasn't nearly as strong mine. Luckily my sister was at the bottom of the stairs waiting for me. If she weren't there to catch me I probably would have gone through the front window.
"Wow, I can't believe how much stronger you are. I never would have been able to do that in my body. Are you okay?"
"Yeah, just a little shaky. How do you walk in these things?"
"Carefully, at least until you've had practice. I think you need a pair of flats if you're going to go anywhere."
"Go anywhere? I'm not going out like this."
"How do you expect to fix this if we can't find Sal?"
"He's the guy who sold me the stuff. Come on sit down; let's figure out what we're going to do. Besides, I want to ask you a couple of questions."
"Okay, just hold my arm, I don't want to fall flat on my face."
Mary sat me down on the couch and sat down on the facing loveseat. I noticed that she instinctively sat with her ankles crossed and her legs together.
"Hey, close your legs, I can see all the way up to my g-string."
"Oh sorry," I said looking down to see that I was slouching down like I usually did when I was tired. My legs were splayed out so much, that I could almost see my crotch while I was sitting down. "So what did you want to ask me?"
"Well, a couple of things. First, aren't you afraid of catching your penis in your fly? I almost did that while I was zipping up."
"It's every guys worst fear, but you learn pretty young to be careful. You learn that even younger than you girls learn to walk in these killer heels. Since, you know what it's like now I'll tell you something I never told you before. I actually got it stuck once when I was little."
"Oh god. How did it feel?"
"It actually wasn't too bad, because I just pinched the skin a little, with the zipper in my footie pajamas. I was terrified though. I ran into the living room, with it hanging out. Mom, Dad, and a bunch of their friends were around. Dad took care of it. Since then I've been really careful. So what's you're other question?"
"Well, don't take this the wrong way, but isn't it small?"
"It does grow you know."
"I've heard, but how much? It was only like an inch or two long."
"God I can't believe I'm having this conversation with you. Do you mean when it gets hard, or in general?"
"It'll grow when you don't want to have sex?"
"Yeah, not as much, but depending on the temperature, if I have to go to the bathroom badly and some other times, it'll grow to four or five inches. If it gets really cold it'll shrink to less than an inch."
"Holy shit, how do you guys live with these things?"
"We manage. By the way, did you take advantage of it when you went to the bathroom?"
"Eeeeewwwww, that's gross. Jerking off my brother's penis, what kind of sicko do you think I am? Wait, what did you do to me?"
"Relax, I meant did you pee standing up? And no I didn't try to jerk off. But I did press a little too hard when I wiped. I'm just used to cleaning my butt, so I sort of got a little feeling."
"Oh, god. I didn't even think to pee standing up. I want to try. Can you help, I don't want to go all over the bathroom."
"No, I won't help. It's not that hard to figure out. Just make sure to lift the seat first. I don't want to get my butt wet. And don't forget to put it back down when you're done."
"Ha, ha. That's real funny. So what does it feel like?"
"What does what feel like?"
"Getting a boner, a hard-on, or whatever you call it?"
"I can't describe it. What does it feel like when you get excited?"
"Ok, point made. Why don't we get you a different pair of shoes, and if you're really uncomfortable with your outfit, a different set of clothes. I'll help you pick something out, and make sure you put everything on correctly. Come on let's go"
Mary grabbed my arm and nearly pulled my arm out of the socket. She led me upstairs into her room and threw open her closet doors.
"Hmmmm, what should we have you wear tonight? It can't be anything frumpy, I do have rep to maintain, but I don't want something that you'll kill yourself in. I don't want to be stuck with your body forever, no matter how much I enjoy being stronger. Let's see you'll wear these boots, they don't have a big heel, but my legs still look great in them. Now we need to find you a bra and different top. Here we go you'll put these on."
I saw her pull a translucent blue bra out of the dresser in her closet. She also had a very small white button down shirt in her hands. I didn't think I would be comfortable with the shirt, but it was better than the tank top and no bra I was dealing with now. I really couldn't understand how my sister could be comfortable with everything flopping around.
"Now for your underwear and skirt. And yes you will be wearing a skirt. I'm not seeing my body at a party in a pair of pants. I think these panties will be good, at least this way if you accidentally flash anyone again, they won't see everything. Now, I guess this skirt will do. I think it's long enough for you, but not too long for me tonight."
"Do I really have to wear this, why can't I throw on a pair of jeans or something?"
"Jeans? I don't wear jeans to a party, no matter how tight they are, or how cold it is outside."
"Fine, fine. But just make sure the skirt is long enough. I feel really exposed right now."
"Now you understand what we go through to please you guys."
"Yeah, yeah, now leave me alone while I change."
"Oh, no I don't think so. I'm not letting you ruin my favorite bra putting it on the wrong way. I bet you haven't even taken one off a girl yet. Do you really think I'll let you ruin one of mine trying to put it on. Besides, it's not like I don't see every part of my body everyday."
"True, I wasn't thinking, I guess it's just a force of habit."
"Ok, now get undressed."
I sat down to take off the boots. I wasn't used to dealing with shoes like that. The highest boots I owned only went up to my calves and had laces, making it easy to deal with them. Mary kneeled in front on me and told me to point my toes towards her, while she took off the shoes. In no time I was barefoot.
"Now lets get the rest of those clothes off of you. If you don't I'll just hold you down while I do it myself. You know I'm strong enough."
"Fine, fine, here they come."
I pulled the shirt of first, giving me a first look at my new body in all it's glory. I started to feel a tingling sensation in my crotch seeing the perky 34B's jiggle around. I jumped around a little to see what they looked like bouncing around.
"Ok that's enough smart guy. Let's get this bra on you before you bounce my tits off. Here you go. Put the strap around your belly and have the hooks in front. Good, now attach the hooks to the smallest eyes. Spin it around so the cups are in front and pull it up to cover your boobs and pull up the straps. Perfect. Now put this shirt on."
I pulled the skirt off and looking in the mirror felt that tingle again, only stronger this time. Without thinking I put my hand to my crotch and felt wetness there.
"Oh no, I'm so sorry, I don't think I did a good job wiping myself. My underwear is wet."
"What do you mean give them to me," Mary said as she ripped them out of my hand. "That isn't piss, you've been getting horny looking at me. You sicko, getting horny looking at your sister's body."
"Not your body, my body, at least for now. I'm sorry I didn't mean to do it."
"That's ok, I know guys are gross and can't control themselves. But at least that means we've only switched bodies, our brains and personalities haven't changed. Now put these on."
Looking in the mirror after finishing, I realized I was dressed just like a Catholic schoolgirl, only the shirt was tighter and the skirt was shorter than proper school skirt. I got that funny feeling again thinking about fucking a girl in that uniform.
"Okay, now that you're dressed let's see about the clothes in your room. I'm not going out dressed in this outfit."
"Why, what's wrong with it?"
"You've got no taste, you put on an orange shirt, black pants, and a pair of brown shoes. I can't even start to tell you how bad this outfit is."
"Fine, let's go to my room and see what you want to wear."
Mary picked out a black T-shirt and a pair of jeans that I hadn't worn in over a year, because I thought they were too tight for me.
"Really, those jeans are too tight for me. I never wear them anymore."
"Yeah, well you're going to wear them tonight. Besides, if they are uncomfortable it won't be you who feels it, but me."
With that she started to undress. When she was got down to just underwear she asked me if I always wore boxers, because she felt odd with everything flopping around. I told her that I hadn't worn anything else in a few years, but might have a pair of tighty whiteys in my bottom drawer. As soon as the words were out of my mouth I regretted them. I'd just told her where I kept my stash of porno. I tried to tell her not to bother that I would get them but she was suspicious, I guess because of how quickly I tried to stop her from going into that drawer.
"Well, well, well what do we have here, 'Cocksucking Bimbos'. What a wonderful title. I guess we're going to see what gets you excited, besides your sister."
I tried to grab the DVD from her, but she pushed me to the bed and ran downstairs. By the time I got there she had already put the disc into the player and was waiting for it to load. I tried to get to the DVD player to remove the disc, but she grabbed hold of me and threw me to the floor. Lying on top of me completely naked, I felt the solid bulk of my old body hold me down on the ground.
"Let me go. You're crushing me."
"I don't think so. You'll just make a run to turn the movie off. I want to see this, plus I want to see if I get a boner and what that feels like."
The movie started a minute later. This was one of those compilation discs with ten scenes on it. The first one was actually my favorite. There was almost no set up to this scene, the girl walked into the room and started to play with the guy on the couch. In no time she had his cock out and was slamming her head down around it.
"Wow, that's a huge dick," Mary said as I felt her grind her hips into my ass. I would really like to get a piece of that."
Just at that moment four other guys walked into the frame, completely naked and all sporting 10" rock hard dicks. There were three black guys and two white guys surrounding this red head with tits a little bigger than my sister's.
"Holy shit, you pervert you like watching a girl get gangbanged. I've never seen a video like this before."
Mary started grind her hips into my ass. Her dick, or rather my dick was rock hard and totally exposed. Almost before I realized what was going on, her dick got underneath my skirt and was grinding up my panty-clad ass. I was getting really excited by this point. Without realizing I started to grind back against her and let out a low moan.
Keeping me pinned to the floor, she hissed into my ear, "You like that don't you, you dirty, filthy cockslut. You want to get taken by all those giant snakes."
Mary shoved her hand between my legs and started rubbing my clit through the schoolgirl panties she'd given me earlier. Slowly at first, then picking up speed she would swirl around my clit, pressing harder then backing off. Within a couple of minutes the combination of her hand on my pussy and her dick on my ass had me just on the brink of my most explosive orgasm ever. Suddenly she stopped and got off my ass. I tried to get up, but suddenly felt a knee pressed into the middle of my back, holding me in place.
"Oh god, that felt good. Let me up."
"I don't think so. Not yet."
She grabbed me by the wrists and pulled my hands behind my back. At first I thought she just wanted show me how much stronger she was now, but then I felt her bind my wrists together. I started flop about, trying to get up, but it was no use. She spun around and tied my ankles together. With another piece of twine, she had me hog-tied.
I heard Mary run up the stairs to her bedroom. It was only a minute before she was back in the TV room. Just as quickly as I had been tied up, I was freed from my bonds. She never gave me a chance to get up. Immediately I was in the same situation as before, lying on my stomach, with my sister on my back, working her dick under the back of my skirt. Again, she started to play with my pussy, bringing me to the brink of orgasm then letting back down. This went on for a long time, so long that we went through another scene of my porno. This one was a straight boy-girl scene. Normally, I wasn't too much of a fan of it, but tonight, watching the guy play with her pussy, while he fucked her face, it made me more and more desperate to finally cum.
"You like this my dirty little whore of a sister don't you. You want me to gag you with my dick like that girl in the movie. Tell me the truth or I won't stop doing this to you. I'll keep you so on edge that you'll be begging for anybody or anything to fuck you in any hole, just as long as they let you come. So tell me the truth do you want me to fuck your ass? Do you want me to make you cum?"
"Oh God yes, anything just let me cum. I'm begging you. I've never needed to cum so ba-."
That was all I could get out before she shoved a couple of fingers into my mouth and started to work them deep down towards my throat. Unconsciously, I started to lick and suck on the fingers that were thrusting in and out.
"Yes, that's the way you Blonde Cocksucking Slut, take it all, I know you like it."
"You want more, right? Nod your head if you like it."
As fast as I could in my awkward position I nodded my head up and down. I couldn't speak, but at least this way I might be able to get what I needed. Mary pulled her fingers out of my mouth and shoved in something else. Whatever was in my mouth was thicker and longer than the fingers she had shoved in earlier. Saliva was pouring out of my mouth and all over my chin and neck. After rapidly fucking my mouth, Mary slowed down and started to probe deeper towards the back of my throat. I coughed, gagged, and nearly puked.
"If you can't take it all I won't give you what you want. Relax your throat."
I tried to relax and whatever she was using slid deeper this time. When it got too deep and she didn't seem ready to relent I bit down, in an attempt to keep from choking.
SMACK, hard across my ass. "No teeth!" Mary scolded. "You bite down again I'll really hit you hard."
"Omay," I mumbled around the object.
Again she shoved it deep. This time fast and hard, I bit down again on the second stroke and was really smacked on my ass.
"Oh you like that cunt. Here's another one for you." SMAAAAAACK again, this time harder. By this point I was mewling around the object in my mouth. "I think the whore likes this too much. You're about to cum aren't you? Don't lie, I'll know."
I shook my head no as much as possible. All I wanted to do was to finally get my release. I guess Mary really could tell that I was close to cumming or just lying in general, because she rammed the object down my throat. This time she didn't pull it away as I started to gag. My throat started to relax as a part of my brain realized that I had no choice in the matter. I felt a pop then it just slid right down my gullet.
"Good girl. You took it. Now you get to see what's been fucking your mouth." My mind boggled as the massive dildo was displayed before my eyes. The purple monster must have 10 inches long and 5 inches around. I couldn't believe that thing had gone down my throat.
"Holy shit, that was incredible. Did I take all of that thing?"
"No, but you got seven or eight inches in your mouth. You could be in your porno that's how nasty you are. Now I know why I've never seen you with a girl before. You love the cock."
"I don't know if I do, or it's something to do with your body, but I did love it."
I heard a clicking behind my back. I tried to move my arms but Mary had put a pair off handcuffs on me. I couldn't move at all. I felt arms beneath me lifting me up. I was dropped on the couch, with my chest resting on the arm.
"Time for you to try the real thing. Eat your cock you little harlot. If you bite me, I'll make you wish you were never born. Don't think that I'll do something to you in your body right now. I plan on getting it back, and I'm not going to do anything to damage it. I think I'll just go see my gay friends and let them do anything they want to me. I'll just make sure it's filmed and show it to everyone one of your friends. Don't think they'll just fuck me and make me suck their cocks. I'll let them piss on me, shit on me, do anything their gay, perverted minds can come up with."
She stripped off her pants and what before today was my dick was waving in my face. Grabbing hold of my ponytail she yanked my head back, forcing my head open. This was it; I was going to suck a dick. Not just any dick, but the one I'd seen every day of my life. Mary didn't want to get a blowjob. She wanted to do what everyone with a dick wants to do. She wanted to fuck something. The thing that was most accessible just happened to be my mouth.
Unused to a dick, Mary didn't start off fast, but pushed it all the way in. Once it popped through my throat, she started to thrust faster and faster. Soon she was fucking my mouth as hard and fast as you would the pussy of a ten-dollar whore. I loved every sloppy degrading moment of it. I was covered in spit from my chin down to my shirt. I felt the dick start to twitch in my mouth and heard Mary start to grunt and moan. I knew she had to be close to finishing at that point. Suddenly, with one violent thrust I felt pubes tickling my nose. I'd taken the whole thing, all nine inches of my former penis.
"I'm cumming. Swallow it, swallow it all. Good cocksuckers always want to keep all the cum they can. Oh yeah, that's good!"
A giant spurt of cum came out, but the dick was so far down my throat I couldn't taste it. She backed off, so just the tip was in my mouth and kept cumming so I could taste it before I swallowed. It wasn't the best thing in the world, but I'd certainly tasted worse.
Panting I looked up at my sister and pleaded with her to let me get off too, but she just looked at me and laughed. I was in for a long night before I could get my rocks off. Still holding onto the ponytail, Mary walked around behind me so I couldn't see what was going on. I heard a buzzing down by my waist. I knew that could only mean one thing. I was about to get fucked by a dildo. My pussy was practically creaming at the thought of being filled up by that vibrating ten-inch monster.
I felt the head of the machine on my ass. Mary fiddled around with speed on the vibrator, first at the lowest setting, then jerking it up to 10. It was moved all over my panty-clad bottom. One minute the tip was pressed between my ass cheeks, and then she slid it towards my pussy and just briefly touching my clit. Mary never let it stay pressed against my sex for too long. Whenever I started grinding up against it, she would move the dildo to another location. I would start to ride the wave to the crest of the orgasm, and then the stimulation was removed or slowed down enough to leave me lying there more frustrated than a five year old staring at the window of closed toy store.
"Oh God, please stop it." Mary pulled the dildo away from.
"No, no. I meant stop torturing me. I need to cum so bad. Please make me cum, I'm dying here."
Mary just laughed at me and got up to get something to drink from the kitchen. Walking back, I saw she stripped of all her clothes. Her dick was rock hard again. I thought, I hoped, I prayed, maybe she wanted to try it out for real now. No luck. She just grabbed hold of the ponytail again and shoved the engorged tube in my mouth. This time instead of fucking my mouth, she wanted me to give her a real blowjob.
"Make me cum again, and I might take care of you. You have to do the work this time. You can't lie there like the lazy whore you are. If you really want to cum you'll prove to me how much you want it."
I started to suck on her dick, my tongue played along the shaft trying to coax the cum from it. Since I knew I always lasted much longer after my first orgasm, I really worked as hard as I could, just so I would receive my reward after. When Mary let go of my ponytail I really went to town. I licked and sucked up and down the shaft and sucked hard on both balls. She was certainly enjoying her first real blowjob. Whenever I put the shaft in my mouth, she thrust along with me trying to get her second male orgasm.
I sucked and sucked for all I was worth. After ten minutes my jaw was starting to get sore. Now I knew why it's called a blowJOB. Hoping to get this over with as soon as possible, I pulled my lips back from my teeth and lightly rasped them across Mary's glans. I heard her rapidly draw her breath in.
"Oh daaaaaammmmmmmmmmmmmmmn, that feels good. Suck me; bitch. I'm so close. Unnnnnnnnnnnnnnnnnnnnnhhh."
She grabbed hold of my head and started fucking my face again. Since she was starting to get used to having a dick, it was much more forceful this time. I was gagging and slobbering, but loving every second of being used by my sister. She made one last desperate thrust and again I was pressed against her pubes struggling for breath.
Just as I felt the semen start to flow through her dick, she pulled out and jerked off all over my face. I was really getting desperate by this time. I'd closed my legs as tightly as possible in a vain attempt to get enough pressure on my clit. I tried to hump the couch like a man might, but realized that was not going to work with my current equipment. Mary could tell that I was trying anything I could think of to get myself off, but knowing it wouldn't work; she just let me keep doing it while cumming all over me.
Gasping, I begged her to get me off now. She just looked down at me, and laughed while slapping my face with her dick. I felt like a girl in a porno, except I was wasn't faking anything. I really loved getting face fucked and now being cum on. Mary zipped up and walked away. I knew this was my chance to do something. Even if I couldn't use my hands, I might be able to get up and ride something to orgasm.
I edged off the couch until I could get my feet underneath me. Looking around the room, the only thing that seemed to fit the bill was the arm of the couch. I straddled that as best I could, working up a rhythm, I was getting closer and closer to the promised land that had been denied to me for so long. It was so exciting that I couldn't help moaning. With each stroke I got louder and louder. Just as the dam was about to burst, I was shoved off my perch.
"What do you think you're doing, slut? Only dirty girls do that. You need to be punished now."
"Isn't that what you've been doing to me all this time?"
"Not by a long shot. I'm really going to have fun now."
She rolled me over so I was slouched on the couch my ass just of the front edge and my legs spread wide apart. I was completely vulnerable to Mary. In my position there was no way to resist her or get away. I just had to resign myself to my situation. My sister pressed the dildo against the huge wet spot on my panties. It hit me like a bolt of lightning. I was writhing trying to get more pressure on my pussy; Mary kept pulling back slightly, drawing me forward. Soon enough, my ass was completely off the front of the couch, only by straining my thigh muscles to their breaking point was I able to stay off the floor.
Mary would wait until I was ready to explode, and then pull away. I was constantly on the brink of a mind-blowing orgasm. Making one more lunge towards the dildo, I went too far and fell to the ground.
"You want cock don't you?"
"Unnnnh, yes please give it to me."
"Tell me what you want, tell me what you need. I won't even think about it, if you don't tell me what you want."
"Please I need to cum."
"Not good enough. Tell me what you need."
"I-- nee-- I need cock."
"Where do you need it? What do you want it to do?"
"I want it in my pussy. I need to be fucked, please fuck me. Oh God, I need to be fucked," I moaned out as Mary renewed her attack my clit. I was in excruciating pleasure. I could just lie on the floor and hope Mary would have mercy.
"I don't think one dick is enough for a slut like you. You'll wear the poor thing out. Well, do you want more than one dick? Do you cockwhore?"
I started to answer, but the dildo was rammed deep, as soon as I opened up. I sucked that rubber schlong like there was no tomorrow. My only thought was to somehow convince her to let me cum. I couldn't move my head very much but I bobbed up and down as much as possible. Just as I thought I was going to get that release I so desperately needed, she stopped stroking my clit, but kept fucking my mouth with the dildo.
"So do you need more than one cock?"
"What was that? You do need more than one cock?"
"What will you do to get the cock you need? Will you do whatever I tell you?"
"Good girl. If you do what I want, I'll make sure you get what you need. Now get up. We need to make you presentable for the party."
Mary got up off of me and dragged me up to her room. I was primped within an inch of my life. She'd decided that the Catholic school outfit she'd put me in wasn't enough. She ripped the blouse off of me, popping half of the buttons. She then dragged my skirt down off my body. I was standing there only wearing underwear and a pair of boots with fat heels.
"Okay, let's see what outfit will be appropriate for a slut, cunt like you. I don't mean to put you in anything I wouldn't wear."
My sister grabbed the skirt she'd had on earlier in the evening when it was her consciousness that was in charge of her body. I looked down at the results and was incredibly excited about going out in public dressed like this. Then my bra was ripped off of me.
"I don't really need that bra. Certainly, with the fun I will have tonight, it will be worth it to destroy that bra."
"No, not fuck you. Fuck my body is the theme for evening.
"What do you mean?"
"I mean that if you want to get off tonight it'll happen at the party. You won't be going up to some bedroom. You'll be fucking anyone who wants you, and doing it in front of the whole party."
"No, I won't do it."
"Oh yes you will," my sister sneered at me, shoving her hand up my skirt. Yet again she played with my sopping pussy. I worked my hips for all I worth against her hand. Just as I was about to reach the promised land she pulled away, yet again.
Pulling up my skirt, she yanked my panties down. "I don't think want to wear these tonight. I think a girl that's as sluttish as you doesn't want anything between her pussy and the nearest dick."
"Please don't do this to me. Just make me cum. Please I'll do anything for you. I'll do all your college papers. I'll give you money, just make cum and don't force me to go to the party, at least not all revved up like this."
"Not a chance ho. You're going to that party and I'm going to get you right on the edge and have a special surprise waiting for you when we get there."
"What'd I ever do to you to make you so pissed at me?"
"Nothing really, but I'm going to enjoy this as much as possible. And I know you won't say anything about this to anyone."
"What makes you so certain about that?"
"Well first, who would believe you about this? Second, even if they did believe you, there will be plenty of people who will have seen you act like the biggest slut in the world. They'll see you begging for their dicks in every hole. They'll see you cum over and over after you jump their bones the second you get there. They'll even hear you beg for their cum. If anyone believes you, they'll know how much of a cock and cumslut you are."
"Ok fine you win. Like always you're right. But, please I am begging you, as your brother, please let me cum. Don't fucking degrade me like this."
"Fine, you want to know why I am doing this to you? It's for all the times you joked about me being easy, all of the little snide remarks about my 'temporary' boyfriends. That is why I am doing this to you. Do you understand now?"
"Okay. You made your point. I'm sorry for everything I said. Really, I am. I understand your needs now."
"No. That's wrong. I know now that you had the same needs, but because you're you, you never had the chance to act on those needs. Also, if you were able to act on them, everyone would just call you a stud, and think you are great. But for me, they think I am just some low dirty slut. I want you to fully understand that, while having more pleasure than you've ever had in your life. That's why I'm doing this to you."
"I understand your needs now. Please don't make me do this. I'll never make fun of you, or any woman who enjoys having sex with different men."
"That's not enough. I want you to really understand how I feel. I want you to know it so well that anytime you hear a guy make that sort of sexist remark you'll react and tell them to shut the hell up. I swear, on our Uncle's soul, if you do this and don't mention it anyone, you are completely safe."
"Okay. I sort of understand it now. I won't tell anyone. I swear. I'll do anything you want to keep this quiet."
"Good, but I will be telling Debbie about the situation."
"NO, don't do that. Please I'm begging you don't tell anyone."
"I know why you don't want me to tell her. I know you have a crush on her. Don't worry about that part of it. She knows how you feel about her."
"What do you mean?"
"Oh for Christ's sake it's the most obvious fucking thing I've ever seen. I mean I don't blame you. She is cute as hell, but it is so goddamn obvious you have a serious fucking crush on her."
"Okay. Fine, I adore her. I've had a crush on her for years. Why do you have to tell her about this?"
"Two reasons. She is my best friend. Second, she is going to help me with my plan."
"Your plan, what do you mean, you plan?"
"I mean my plan to get you fucked beyond you wildest dreams. I'm going to call her before we leave for the party to set up the fucking of your life. I'm already known as the 'good-time girl'. Those guys might be surprised that 'I'm' going to be gangbanged in public, but I've already fucked most of them."
"I've screwed pretty much all of the guys at the party, and by the way, it will be a surprise for you the guys that will be there. I've even been gangbanged by some of them, but I've never been gangbanged in public like you will be tonight."
"Please don't do this to me. I'm begging you."
"You're begging me? Don't waste your time or energy. You're going to fuck all of those guys and probably some of the girls too."
"Fine. Let's get this over with. Let's go to this party. I know it's the only way you'll give me relief."
"Oh, no. Not yet. We still have time until we have to be there. Also, I don't think you want to walk over there without a top? Besides, I have to talk to Debbie about my plan." I couldn't believe it in my excitement I'd completely forgotten I was naked from the waist up.
"Fine whatever. Just get it over with." I thought that this was where her plan would unravel. How would she be able to convince Debbie that this thing happened to us? She would be calling from her phone with my voice, with Debbie coming over to see both of us together apparently acting like normal.
As she slid the keypad out from the phone, I realized my sister had thought this out. She was going to text Debbie, to at least start the discussion.
"Well, I got in touch with Debbie. She'll be here in a few minutes. Don't worry, I've told her that something happened and I want her to ask questions that only I would know the answer to."
"Yes, that's right. Fuck you. Fuck you more than you've imagined is possible. Now let's get a top on you."
"Fine, whatever. After that can we just sit and relax for a while. I admit I've done some shitty things over the years. Please, just let me relax until Debbie gets here."
"Okay. I'll give you the fifteen minutes, but we are watching more of that porn that we had on earlier. Now let's see what we should put on you. It needs to be a little slutty, but allow easy access and removal."
Rummaging through her drawers she quickly came across what she was looking for. "This peasant halter top ought to do nicely." She pulled it down over my head, and lightly tied up the back. "Nice easy access, but just be careful bending over, it's tied so loose your tits will be on display from the sides, underneath, and the top. So now that you're ready let's go downstairs to wait for Debbie."
Mary put the DVD back on and skipped through all the sections we'd watched before. Soon enough she got to the blow bang track, before tonight I enjoyed watching this scene, but tonight, imagining myself as the girl, I was going wild. Watching her on her knees, surrounded by a bunch of guys with big hard dicks was making me more excited every second.
"You wish you were the girl don't you slut?"
"Mmmmmmmmm. I do."
"Get your hands away from your crotch, unless you want me to go back to work on you. You can play with you tits if you want."
Reluctantly I pulled my hands away from my crotch and let them fall onto the couch on either side of me. I watched, as the girl in the porno would jack off two dicks while being face fucked by a third. Every 30 seconds or so she would change position and take another cock down throat. Soon enough she got to the biggest one in the scene, a fat cock that was a couple of inches longer than any of the others. It looked like it was a foot long, and was so thick she couldn't wrap her hand all the way around it.
I started to bring my hands back to my crotch, when I remembered Mary's threat. Instead of stroking my clit, I brought my hands up to my chest. Brushing my nipples, I realized how much more sensitive I was in my new body. Pinching my left nipple I felt a little twinge down in my crotch. Thinking that I might be able to get my relief I furiously pinched and tweaked my nipples.
Two of the guys picked the girl up and brought her to a chaise lounge much like the one in our house. Laying her down on her back with her head off the lower edge, one of the guys kneeled in front of her head. Seeing the massive dick in front of her face, she opened her mouth and stretched towards the fat 10" monster. Two other men grabbed her arms and brought her hands to their dicks.
I wanted nothing more at that moment than to be that girl. All I wanted, no all I needed was to pleasure big dicks and get my rocks off. Seeing her lying there, moaning around the first dick, was making me incredibly horny. I was grabbing harder and harder at my tits. Suddenly I let out a gasp as I was nearing the explosion I needed so badly. Mary must have heard me; because she jumped up off the chaise she was sitting on and knocked my hands away.
Holding my hands above my head she asked, "So that's what you want to do, is it? You want to be face fucked while servicing other cocks. I'll bet you want to have all three holes filled and jack off two other guys. You're turning into a gangbang slut right before my eyes aren't you?"
I couldn't answer the question. Did I really want to get fucked by a room of guys? Was this experience in my sister's body turning me gay, was it just a physical reaction from being in her, or was there some bit of her subconscious left in her perfect body? I didn't want to know the answer to these questions, I was a little afraid of the answers. This wasn't coming to a realization about ones self gradually, but possibly swinging from one orientation to the other not in a single day, but in just a few hours.
"Well what's your answer little sister?" Mary asked me. After waiting for an answer, she sat down and placed me on her lap. Wrapping one arm around my middle to pin my arms against my sides, she reached under my top to play with my chest.
She gently rasped a nail around my breast, in smaller and smaller circles until she was just on the edge of my aureole. Switching to the other side she did the same thing. Two more times she did this to each breast, before she released my waist and pinched both nipples hard. I was in heaven. I was watching a porn star get face fucked until she was nearly insane with pleasure, while I was giving my old body as good a lap dance as I possibly could trying to finally achieve the orgasm I'd been denied all evening.
Just then Mary pushed me off her lap onto the couch, and pinned me on my side, slipping three fingers into my gasping mouth. "You really thought you were going to cum that time didn't you?" She asked.
I could only moan and shake my head as she slowly, but firmly fucked my mouth with he fingers. Leaving them pressed deep inside me, I started to suck on them and use my tongue like I was trying to get a guy to cum for me.
"Don't worry my little cocksucking, gangbang ho, you'll get to cum soon enough. Now sit up," she said, taking her fingers out of my mouth. "When Debbie gets here you better refer to me as Dave until she knows what happened. If you don't, I will come up with some sort of appropriate punishment. I don't know if it will be something I'll do to you tonight, or if it will be something I do in, or to your body, but you will regret it. Do you understand?"
"Yes," I gasped as she removed her fingers from my mouth, "don't worry I'll go along with it. I wouldn't have wanted to be on your shit list before, but now that I know how perverted your mind can be I really don't want to piss you off."
"Good you're starting to learn. In fact, I'll give you a little reward for that. I'm not going to make you cum, but I won't do anything else to you at least until Debbie gets here."
We stayed on the couch, watching the scene together. As the guys were getting ready to climax over the girl, I leaned in towards my sister and started to rub her cock through her tight jeans. This was the first time I'd instigated sexual contact with her. It actually almost felt natural, with the obvious exceptions of it being my sister, and my body that I was feeling up.
Her dick was rock hard, I thought this was the time to get my revenge for all the torture she'd put me through up to that point in evening. I massaged what now seemed to me to be a pretty large dick while the guys were jerking off on the girls face. I heard Mary's raspy breathing as she was working her way to orgasm. I kept up my rubbing as the next scene began. This was one I always liked.
It started off with two 18 year-old girls feeling each other up on a basement couch, while a party was going on upstairs. As they started to get hot and heavy two guys came downstairs. Seeing the two lesbionic partygoers, they decided to try their luck to get lucky.
This being a porno, it only took about thirty seconds for them to convince the girls to let them join in the fun. As they girls were kneeling in front their guy, four more guys came downstairs to look for their friends. They quickly joined in the fun, (it was a porno after all) the girls were soon each pleasuring three guys. When the girls stated to give a joint blowjob, I got a reaction out of my sister. She was really enjoying this part of the scene. I would rub hard for two or three beats, then lighten up for a six or seven. Each time I went through the process I would start to switch the ratio. Eventually, I would rub hard for seven beats and let up for two. I really had Mary going now. Knowing my body, I knew this was the time to stop and see what she would do.
"Hey, I was almost ... there. Why'd you stop?" She grabbed my hand in an attempt to make me rub her. Knowing that I couldn't pull away, I just relaxed my hand and forced her stroke herself using my limp hand.
Even though I'd made myself incredibly excited and horny I was enjoying giving her a taste of the medicine she had been giving me so much this evening. I loved the thought of her having to deal with blue balls for the first time. Unfortunately for me, she knew her body as well as I did mine. Not wanting to get me off, she forced one had between my legs and pressed the palm against the pubic bone. The other one went to my right breast. She started to pinch and twist my overly sensitive nipple. Getting excited I started to press up against her hand trying to get myself off. In my excitement, I instinctively rubbed on her dick.
Just then the doorbell rang. "Fuck," we both gasped in unison. We knew it could only be Debbie.
"Go get the door. I can't greet Debbie with a boner trying to tear through my pants. Just remember not to say anything to her about the situation."
"Fine, fine. I'll get it."
Opening the door to my crush of the last three years in the body of her best friend was a bizarre experience. I was greeted with a monstrous hug.
"Hey, what's up?" She asked in her usual perky voice.
"Oh, we'll talk about it in a minute. Come on in and sit down. Dave is here too."
"Okay," she answered slowly. "You've got me a little concerned. He isn't going to profess his love to me or anything, is he?"
"No, no don't worry sh-- he is going to the party with us. Come on, the sooner we get this over with the better. I'll just tell you it is a little odd, very interesting, but odd."
She walked ahead of me into the living room. As she walked ahead of me, I couldn't help but admire her shapely ass encased in a pair of skintight jeans. This was one of the first comforts I'd had since I woke up from my nap earlier. As long as my sister wasn't a lesbian, then there was some part of my brain still functioning normally.
"Hey Dave what's up?" Debbie asked, in the pause before my sister realized she should answer to Dave, Debbie turned towards to the TV to see what was so engrossing. "Holy shit. What the fuck are you watching?"
"Huh, oh sorry," my sister answered quickly in her confusion, "that was Mary's idea."
"Oookay, whatever. That is hot. Anyway, Mary, should we go upstairs?"
I looked over at my sister to see what she wanted me to say. She just sort of shrugged and gave me a look telling me to go ahead. "Oh, no. It involves Dave too," I said.
"Okay, all this mystery is getting to me," Debbie answered. "What the hell do you need to talk to me about?"
"Okay, here it goes," my sister said. "Do you remember what Mary said about questions only she could answer?"
"Okay, well go ahead and ask a question. Just make sure it's something that has a specific answer. No yes or no questions," Mary answered to this statement.
"This is really strange. I like both of you very much, but one of you better tell me what the fuck is going on; and to be honest I would prefer it was Mary," she said looking at me.
"Okay", I answered. "Just ask the questions that I wanted you to think of in the text."
"This is fucked up, but I trust you, so here it goes. First, who is my secret crush?" I asked.
Mary answered after half a second, "Me. That's a really fucking easy question, no offense."
"Really," I answered, out of instinct.
"Okay, what the hell is going on? Mary," she answered, looking at me, "why the hell are you guys talking like your consciences have been switched."
I looked over at Mary to see if she wanted me to do, or say anything. I got a slight nod from her. If you weren't her baby sitter for many years, you wouldn't have caught the request for me to take over.
"Okay, listen, something really fucked up had happened to ... Dave and I."
"Well, I can tell that, if you are watching porn together. Especially something this graphic."
"Very nice," I answered. "Just ask the questions I wanted you to think of."
"Why do you want me to ask these questions? You know the answers to them. It's not like you're someone else."
"That's the whole point," Mary replied. "Earlier, we took some X I got from Sal. Somehow, it caused us to switch bodies."
"What do you mean?"
"Well, I look and sound like Dave right now, yes?"
"Yeah, you do," she tentatively answered.
"And that looks like Mary on the couch?"
"Yes, just tell me what the hell you mean in plain English. You're confusing me."
"Fine, somehow our brains, or bodies got switched," Mary said.
"What do you mean?"
"I mean, I am actually Mary," she responded through my body. And "she", is Dave."
"Holy shit. That's too fucking bizarre! You have to prove it to me though."
"I know; that's why I asked you to think up questions that only I would know."
"Okay, okay; let me think. I know; who did I lose my virginity to, and where?"
"To Joe Thomas, underneath the stage in the auditorium. Any more questions you want to ask?"
"Yeah, who's the last guy you fucked?"
"Just answer the question. I'm having fun with my brother. He is so horny, he would fuck Bob Davis," I named the most slovenly, smelliest guy in our school. "He might get a little pissed, but that is part of the fun for the evening."
"Fine, it was Chris Iracane, Jim Miller, and Nick Powers." Debbie answered, naming my best friend and two other guys.
"That bastard," I spit out.
"Why? Because he had sex with a girl who wanted it, or because I fucked three guys?" Mary retorted.
"Because you're my little sister."
"Is it any different to want to fuck your sister's friends? Or if you want to have a ménage a trios?"
"Yes, it is."
"That would mean, if Debbie wanted to fuck you she couldn't because you are her friend's brother."
"Again, you've made your point. I'm just a sexist asshole."
"No, you aren't. But like all older men you're over protective of the women you feel responsible for. That is a good instinct, but you just need to know when to let it go. So, anyway Debbie, do you need to ask anymore questions?"
"Well yes one more, just to make sure. Who is my secret crush?"
"Are you sure you want me to answer that question?"
"Yes, if there is any time for this to come out, it's now."
"Fine, it's Dave. I've adored you for years."
"Yes, I believe you guys. What's the plan? I mean how are you going to fix this issue?"
"I don't know," Mary answered, "but that's something I'm not going to worry about until we wake up tomorrow. In fact, I sort of enjoy having this body. I like being this strong, also, I'm going to enjoy fucking you tonight."
"Yes, you just said that you want to fuck my brother, right?"
"Well, what better time than when he is being fucked by every guy and most of the girls at the party."
"Sounds good to me."
"Hey," I interjected, "what about me? I've dreamed about being with you for years."
"Well, if you guys switch back into your own bodies, I'll fuck you until you're begging for mercy, if not well, we'll figure it out."
"We'll figure all that out later," Mary answered. "If you keep quiet about the situation at the party, I'll fuck you with my brother's body. You can see how big his dick is."
"Deal. When are we going to the party?"
"Oh, I thought we would leave in a few minutes, but we just have to get my brother all hot and bothered before we leave. I want him to be tearing off his clothes the second he walks into Rachel's home."
"Ok. How do you propose that?"
"We're going to leave now. When we get close, we'll get him nice and excited. Then you'll go in ahead of us and arrange for the guys to be ready to gangbang Mary's body."
"That sounds good to me as long as Dave has no problem wit it."
"Oh he doesn't, just ask him."
"I just want to cum. I don't care about anything else. Mary has gotten me so excited, I'm begging you to let me get off."
"Are you sure you want this?"
"Yes, I'll do anything to get off."
"Okay then, I have two conditions."
"What are they?"
"First, I want to fuck Mary tonight. Second, if things go back to normal, I want to fuck you tomorrow night, especially now that I've seen how big you cock is."
"Huh," I asked Debbie.
"I can see your dick trying to explode out of ... Mary's pants. You're fucking hung. If you didn't know that, then I sort of feel sorry for you."
"Listen, what I said was the truth. I've wanted to fuck you for quite a while. The only reason I didn't make a move was because I've been restricted by tradition."
"While I'm stronger than you, and have an ally who can really dominate you, I think I'll take advantage of your body."
"What do you mean?" Mary blurted out.
"You're fucking hot. I've wanted to fuck you since I met you, even if I was too young to realize it at the time."
"You never knew that I'm bi?"
"No," Mary answered. "I never had a clue. I understand why you didn't say you like me. It's the same reason you haven't told Dave you want to fuck him, but why didn't you mention this to me."
"Because I didn't want you to guess and freak out. I would rather be frustrated and have you as a friend, than tell you how I feel and lose my best friend. I love you, in both ways."
"I don't know what's going to happen in the long run, but I can promise you two things. First, I'm going to fuck you tonight. Second, you can play with Dave tonight. It'll be after he gets fucked, but it's your choice if you want him cleaned up first."
"Oh, I think I'll take him when he's a very dirty girl. I've always had the hardest time keeping myself from fucking you when you were covered in cum after your gangbangs."
"That sounds kinky, I'm sue Dave will love it. Oh shit, we've got to go. I don't want the guys to start fucking any of the girls before we get there. I want them nice and fresh for my brother."
